Re: Comfort - X10 vs relays

["Simon Coates" <ecolume@xxxxxxx>]

RS components also sell Crydom SSR, RS ref 376-3776
Also worth looking at standard DIN rail relays eg. RS ref 184-5450 which is
a 12Vdc (24mA) operated relay which will switch 5A at 240Vac, also
available
with lamp indicator, good thing is that at 9mm they are 1/2 standard DIN
spacing and cost just over £7.00.

I agree with John, definitely keep your lighting system separate and
'stand-alone', yet integrated with your HA.  ie. lots of LD11s and AD10s
with momentary switches to manually control your lighting, letting Comfort
do the automated stuff.
